QA Strategy & Quality Governance

Without a solid QA strategy, testing becomes a bottleneck instead of a safeguard. We lead with a defined plan that sets KPIs, coverage targets, tooling standards, and ownership so QA is aligned with delivery from day one.

Our process draws on senior QA leadership and enterprise delivery experience to identify risks early and design coverage that scales. The result is predictable quality, faster releases, and fewer expensive surprises mid-project.

Manual & Exploratory QA

Automation can only find what it's told to look for. Critical issues often hide in real-world usage. Our senior QA engineers manually explore flows, devices, and conditions to uncover usability gaps and edge cases before your users do.

We combine this with domain expertise in complex enterprise environments to validate scenarios that automation misses. That means cleaner releases, better customer experiences, and fewer post-launch fire drills.

QA Automation Frameworks

Regression bottlenecks slow delivery and raise risk. We design low-flake, language-agnostic automation frameworks that integrate seamlessly with your CI/CD stack and evolve with your product.

Because our engineers have built automation for large, complex systems under tight deadlines, our frameworks reduce test maintenance and accelerate feedback loops. You release faster, with confidence in every build.

Functional & Regression QA

Every new feature has the potential to break something else. We create and maintain living test suites that adapt as your product changes, catching critical defects before they impact customers.

Our teams work as embedded QA partners, aligning sprint by sprint with your development cycle. The outcome is fewer production incidents, higher stakeholder trust, and more time spent building instead of fixing.

Performance & Load Testing

Slow or unstable systems cost more than just reputation. They inflate infrastructure spend and block growth. We simulate peak traffic, stress-test APIs, and analyze bottlenecks across your architecture.

By combining advanced tooling with engineers experienced in high-scale environments, we pinpoint and resolve performance issues before launch. Your users get responsive, reliable software no matter the demand.

Security & Compliance QA

Security gaps and compliance failures can stall releases or cause costly breaches. We embed vulnerability scanning, penetration testing, and compliance checks from the earliest stages.

Our QA covers industry and regulatory standards like SOC2, HIPAA, and PCI-DSS, adapting to client-specific protocols. This builds stakeholder trust and keeps releases audit-ready from day one.

Mobile & Cross-Platform Testing

A flawless user experience across devices isn't optional. It's expected. We test on real devices, OS versions, and network conditions to ensure functionality, responsiveness, and accessibility everywhere.

Our approach accounts for global usage patterns and accessibility requirements, giving you a consistent, high-quality experience across platforms. That means fewer app store complaints and higher adoption.

API & Microservices QA

Modern systems depend on reliable service boundaries. We validate API contracts, simulate failures, and virtualize dependencies to test without blocking delivery.

Because our QA engineers work in complex, service-heavy architectures, we prevent breaking changes from reaching production. This keeps integrations stable, accelerates delivery, and reduces costly rework.

Why work with us

How we work

Here’s what makes us easy to work with and hard to replace:

From code quality to compliance, we’ve optimized every part of how we work to support high-performing engineering teams. For you, that means clearer communication and smoother delivery. Plus, get peace of mind from having a development partner you can depend on.

  • Vetted Senior Talent
    We hire the top 1% of over two million applicants, so you only work with the best.
    We give you engineers who’ve already proven they can deliver. Our rigorous evaluation process includes technical tests, English assessments, soft skill screening, problem-solving simulations, and more. Out of over 2 million applicants who apply yearly, fewer than 1% get the chance to join our team. This is how we ensure you get highly qualified developers who are experts in their fields.
  • Timezone Aligned
    We work your team’s hours, which creates faster feedback loops and fewer blockers.
    Our nearshore software engineers share your workday, answering Slack messages, joining daily stand-ups, and presenting demos in real time. Project management is streamlined, questions are answered quickly, blockers are resolved as they come up, and simple code reviews take minutes, not days.
  • Proficient in English
    Our engineers have strong English skills, so communication and documentation are clear.
    Our engineers have 8+ years of experience collaborating with US teams. They excel at articulating complex technical concepts to diverse stakeholders, producing meticulous documentation, and driving technical discussions. This eliminates the ambiguity common with global teams.
  • Full-stack Capabilities
    With expertise in 100+ technologies, we have every specialist your project requires.
    We cover architecture, development, testing, DevOps, and everything in between—reducing hand-offs and creating better architecture decisions for a smoother path from concept to production.
  • Scalable Teams
    Our bench strength lets you scale engineering teams to meet new demands in weeks.
    With 4,000+ engineers on staff and thousands more in our pipeline, we can spin up pods or scale multiple teams across your company in days—so you hit aggressive timelines without bottlenecks.
  • Standard MSAs & SOWS
    We’re easy to onboard because we work the way your legal team expects us to.
    Because we’re based in the US, we follow the same legal standards your team already trusts—using MSAs, SOWs, and documentation that fit your procurement process.
  • NDAs & IP Protection
    We take data and IP seriously, with full protection baked into every engagement. 
    Every engagement begins with a mutual NDA and clear IP ownership terms. Our secure workflows and confidentiality protocols also protect existing codebases and proprietary data.
  • Enterprise-grade Security
    Our devs follow security protocols that meet even the strictest enterprise standards.
    Our engineers work only within the systems they need, using strict access control, audit-friendly workflows, secure repository storage, and more—bringing enterprise-grade protection to every engagement.
  • Managed Delivery
    We actively track our devs’ work to make sure they consistently meet expectations.
    Delivery managers monitor progress, resolve blockers, and report regularly, so you never have to chase updates or second-guess performance.
